Goals,
1. PC that would last four years or so (with upgrades).
2. General use, development, and gaming (GW2 & Witcher 2).
3. Should run cool, be very stable, and have some room for OC (later).
4. Strictly Intel for CPU and NVIDIA for GPU. (i7 is too expensive)
5. Sweet spot @ ~1000 USD
6. Everything will be ordered Friday

Concerns,
1. Difficulty of build (never done this before).
2. Components not fitting together and/or not being compatible with each other.
3. Bottlenecking performance somewhere.
4. Forgetting some important component.

With help of Newegg, Google, and YT, I have made the following selection,

personally I'd switch out the PSU with one that's at least silver certified, but besides that everything else looks fine

you shouldn't really have any spacing issues with a standard ATX size build and the parts your choosing

Alright, will take advice on the PSU.

One more thing, what about noise?How bearable would it be to, say, have such a PC at high load in your bedroom overnight? (Although a more likely situation would be to download steam games overnight doing nothing else)

the better PSU will be worth it, every little bit helps with the power efficiency IMO. your electric bill will thank you in the long run

and as far as the noise goes, it all depends on a few things, 1. the noise rating on the psu (the psu is usually the biggest factor, usually it will say if it's a super quiet PSU). 2. your CPU fan (and it looks like the one you have chosen will be just fine in that regard). 3. the fans in the gpu

over all if looks like the build you have laid out will be pretty quiet so you shouldn't have to worry too much (and honestly if you're anything like me, a little white noise at night is soothing )

Firstly that's a sweet looking build right there. You will be able to easily overclock that to 4.5GHz but not with the cooler in your spec there. The Noctua NH-D14 air cooler should easily give you temps of 60-70 under max load:

A little pricey but your other option would be water cooling. With the above cooler, those GSkills will not have enough clearance under the fan so switch them out for the following Corsair low profile DIMMs (don't be put off by the 2 x 2 egg reviews, seems like those idiots didn't set their BIOS settings for the DIMMs to X.M.P profile):

I've been through a fair few PSU's in my time including noisy PSU's with coil whine issues. I'd avoid Corsair/Seasonics new range as they seem to be plagued with coil whine issues. The XFX PSU above, although double your current specced PSU's price, will last you a good while. It's innards are made by Seasonic but from a range not affected by coil whine noise issues.

You shouldn't really hear that machine above the case fans/GPU fan when its under load. I've never looked into Rosewill cases before but that one seems to have decent reviews so I wouldn't assume you'd have anything to worry about on the noise side.

Your BD drive doesn't have the ability to burn DVDs or CDs which could possibly be an issue. I very rarely do it, but if you're going to have the drive you should probably get one that can burn DVDs and CDs at least. $25 more gets you one that can burn BD, DVD, and CD.

Also, check if you live near a Microcenter. They have the 3570K for $40 less than Newegg and you also get $40 off a compatible motherboard. I believe most managers will match Newegg's prices, too. They have a 60 day return policy (that in my experience has been no questions asked) in case anything goes wrong.

You also don't have an OS listed. If you plan on using Windows don't forget to take that into consideration.

The 3570k is fine. The k denotes the CPU has an unlocked multiplier thus allowing overclocking. Non k processors cannot be overclocked.

If your not planning on overclocking it by much, I'd stick the the stock cooler & your original choice of ram but my suggestion was based on you wanting something that'd be competitive and give your decent performance for a few years.
